A'Appliance md :july s, ieee, serial To all whom t may concern: Y

Be it known that I, JOH'N HOWARD Taf BLER, a citizen of the United States, residing at Washington, in the District of Columbia, have invented a BeltFastenen of which the following is a specification.

My invention is an improvement in fastening devices employed for `connecting the ends of 4machine belts, as forinstance'fan belts used in connection with automcbile engines.

The primary object of my invention is to provide a belt' fastening deviceof this characterl which will be simple in construction, easily applied to permit of an accurate adjustment of the belt between 'thepulleys before fastening the ends'thereof together, and when applied will not interfere with the proper operation ofthe belt or smooth run-V ning of the same on the pulleys.n

A further objectfof my invention is to provide a fastening device whichmay be advantageously used for connectingtheends of a belt .or band made of cotton webbing to thereby providea cheap', strong and durable fan -belt for automobile engines that-is not only inexpensivefbut may be readily and convenient-ly` applied by son.

A further object of my invention is Ato provide a belt fastening devicethatwill ccnnect the ends of the vbelt in such manner that both the belt and fastener will opg` erate in grooved pulleys, the beltassum ing a shape in cross-section lto correspond with the shape of the peripheries of the pulleys over which it' runs. Y f Y i In the drawings:

' Fig. 1 is a sidel elevation illustrating an application of my invention to a belt `used in connection with: groovedpulleys.

Fig. '11 shows theapplicaticn of the fas-A illustrated my invention applied to a narrow belt, A, such as used in connection with automobiles, sewing machines, ctc., employing grooved pulleys B and C; but as hereinafter explained the device may be used also `for connecting the ends -of atbelts In carryingDout my inventionr the fasten-Y ing device, is formed from malleable metal in any suitablev manner, being-preferably stamped from sheet metalyand in each instance'is. of a single piece topresent opposite longitudinal side pieces 1 5 15, crosspieces 16 16 between the iends of said side pieces, and intermediate cross-pieces 17 and 18 spaced apart and from the vendcrosspieces te provide lslots V19 19 and;Y 20 through which the .ends ofthe Vbelt are threaded in the manner hereinafter described; 4the slot 2O being of sufficient width to 4receive two thicknesses of the .belt-'whilethe lslots.

19 19 arenarrow for the passage there? through of a single thickness of said belt. It will be noted that the side peces'depend at substantially right angles from the: crosspiecesconnectedat the upper ends thereof, preferably on ,a line with each other and that saidside pieces are bent outward and inward Vwhereby to facilitatethe operation of clamping the device upon the'cong nec-ted ends of the belt.

.l In applying'the fasteningdevice to a-belt the ends ofthe latter are connected in looped engagement with thev cross-pieces 17 and 18,

respectively, by passing said ends of thev belt up through the slot E2()v and out in opposite directions through the slots 19 19,

so that theterminal portions a will lie be-.

tween `the end Across-pieces 16 and bodyof the belt, as clear-ly ,illustrated in Fig.-1-l of the drawings, When V'the belt is loosely connected to the fasteningdevice in-this manner it may be put on the pulleys fand adjusted between the same by simply pulling upon either'oneor both of-the terminals a,-

vThe evice is made of thin metal compared to the thickness of the belt, and the length'and width of the slots 19 19 and 2U Vand in this instance the strip of cotton webbing is tightly twisted upon itself 'from one end of the fasteningA device to the other. In forming this belt, one end ol the material,` a'sc'otton webbing, is connected to onel end of the fastening; device as hereinbefore described and from this connection the strip. of material is tightly twisted upon itself for the entire 'length' of. the belt, being then pulled upon to tighten the twist, and after the other end is connected 'to the asteniw` device the latter is clamped upon lintbthef'material' to provide round jointLcorres'ponding substantially with the dizirneter of `the belt. In lformingthis solid belt the length of the same maybe adjusted either on -or off the 4pulleys by pulling on the terminelsof the :strip yzitter thek latter hes been 'twisted 1115011, itself und the ends thereofuconne'cted' to;I the opposite' ends of tliefas'tening ldevice prelimlnary` toy claniping Said fastening device to make a secure andsolid connection. This solid belt is of peculiar advantage inluse in connection Iwith' light machinery, Vlsuch Aas -auvton'iobile fan` belts, sewing machines, 4&c., and when made of cotton 'webbing provides a cheap belt that is strong and, durable as well as possessing a degree of elasticity 'thatl willy increase the effectiveness `of the belt.

will be 4obvious thefastening device. may housed yfor connectingy a. belt in at least three ways-Lto provide a fhttl'ielt` a curved belt, and a solid belt-and in each'instanee permits of the beltbcing accurately adjusted between the pulleys.4 Furthermore, in each instancethe rn'eterial of the belt may be ,cotton webbing? which inexpensive an possessesy thev required strength. and dura bil- .ity;`.bu`t 'bit course other material may be yusedand connected by the fastening device.
